Hi,
I have a requirement to open word 2007 document with content controls in it in SWT. I have used org.eclipse.swt.ole.win32 classes for this.
I have followed following procedure to open a document
1. Created a new view in my application extending from ViewPart
2. In createPartControl method , I have created a OleFrame in the parent composite. Added File and Windows menu on the frame.
oleFrame = new OleFrame( parent, SWT.NULL );
oleFrame.setBackground( JFaceColors.getBannerBackground( oleFrame.getDisplay() ) );
IMenuManager fileMenu = AIFUtility.getWorkbenchWindowMenuManager().findMenuUsingPath ( IWorkbenchActionConstants.M_FILE );
oleFrame.setFileMenus( new MenuItem[] {((MenuManager)fileMenu).getMenu().getParentItem() } );
IMenuManager windowsMenu = AIFUtility.getWorkbenchWindowMenuManager().findMenuUsingPath ( IWorkbenchActionConstants.M_WINDOW );
oleFrame.setWindowMenus( new MenuItem[] {((MenuManager)windowsMenu).getMenu().getParentItem() } );

3. Created a file
File file = new File("D:\\Demo\\ContentControl.docx");
4. Created a new ControlSite
OleControlSite oleControlSite = new OleControlSite( oleFrame, SWT.NONE, file);
5. Activated a control site
oleControlSite.doVerb( OLE.OLEIVERB_SHOW );

After this new View open is opened and my application menu bar displays only File and Windows Menus (as set in step 2)
6. When I close the view I am performing oleControlSite.deactivateInPlaceClient(); and disposing the oleFrame
7. Once dispose Menu Bar disappears from the application.
8. Same thing when I do with the OleClientSite instead of OleControlSite, thing works fine and applications old menu bar (with File,Edit,View,Window,Help menus) is restored when new view created by me is closed.

I need to use OleControlSite as I have to take advantage of events for content control listeners, which I believe I can do only if I use OleControlSite.
